Complete 5kw Off Grid Solar Power System 380vac Home Use

Complete 5kw 48vdc 220vac 380vac Off Grid Solar System Home Use

Description

Off Grid Solar System is widely used in areas without electricity, power instability, islands, communication base stations and inconvenient wiring for street lights or monitoring systems. The photovoltaic array converts solar energy into electricity when there is light, and stores the electricity in the battery bank through the solar controller; when there is no light, the battery bank discharges through the solar controller to supply power to the DC load, and can also reverse the discharge into AC power through the inverter to supply power to the AC load.

Design of Off Grid Solar System

• According to the load size and type, single-phase 220V or three-phase 380V, the rated power of off grid inverter is determined.
• According to the discharge time of the energy storage battery required by the load, determine the size of the energy storage battery (such as how many kwh to store).
• According to the load power consumption (how many kilowatt hours of electricity) and the local sunshine situation, select the board with high power.
• The size of charge controller is selected according to the size of photovoltaic panel and battery voltage.
• Supports, cables, etc. (installed on the roof or floor).

Application

• Type: Off Grid Solar System

• Areas without electricity such as mountainous and pastoral areas, border guard posts, communication base stations, island power supply, or areas with inconvenient and high electricity costs

• Household solar power supply: used in remote areas without electricity such as plateaus, islands, pastoral areas, border guard posts and other military and civilian life electricity, such as lighting, TV, recorder, etc.

Together with our customers and suppliers, we have been partners in solar battery industry for 12 years and have supplied over 20 kinds of patent solar systems for home and abroad.

In 2008, we established FairylandSolar^TM and won our first solar home system project--“GoldSun” project for whole Shaanxi province which was a famous big project appointed by Chinese government. During 3 years installation, we were always moved a lot when people showed true smile when lighting their home. They should carry a heavy battery and walk hours home, so aftersales is so difficult that pushes us to supply high quality products with long lifetime. We invested gel battery production line with a 50 staff team who has 20 years production experience for AGM battery. For the enough good quality and reasonable price, we becomes a stable supplier for solar projects, OEM for them.

In 2018, as the rapid development of lithium battery, we established CASISOLAR^TM that started a team only for packing lithium batteries. During the past 3years, we found the wide difference between price and products. As government promotes “ giving retied battery a second life” , some make a profit in troubled situation, providing retired cells for solar making great lost in a long term or even has personal safety hazard.

So in CASISOLAR, we don’t think it is 100% safe to use retired battery cells. We only accept cells at Great A with 5 years more warranty. We didn’t grow up quickly but we harvest every customer we have cooperated. We always enjoy and appreciate troubles met during every cooperation, and give great enthusiasm and confidence.

Our mission is to provide solar energy at low cost over a long lifetime.
